Atom x5-Z8330

2016

Why buy it

✅Integrated graphics onboard with Intel HD Graphics (Cherry Trail), while Core 2 Duo E8135 needs a discrete GPU.

Trade-offs

❌Fewer obvious downsides in this matchup outside of normal market pricing swings.

Core 2 Duo E8135

2009

Why buy it

Trade-offs

❌Lower PassMark (1,020 vs 1,025).
❌Launch MSRP is still $200 MSRP, while Atom x5-Z8330 mostly shows up through inconsistent older-market listings.
❌No integrated graphics, while Atom x5-Z8330 can still boot and troubleshoot without a discrete GPU.

Quick Answers

So, is Atom x5-Z8330 better than Core 2 Duo E8135?

Yes. Atom x5-Z8330 is the better all-around CPU here. It gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data, 0.5% better PassMark, and the stronger long-term platform, which is enough to make it the stronger overall pick.

Which one is better for gaming?

If gaming is the priority, Atom x5-Z8330 is the better pick. According to our tests, it delivers 0.2% more average FPS across 50 shared CPU game tests.

Which one is better for streaming, content creation, and heavy multitasking?

For streaming, content creation, and heavier multitasking, Atom x5-Z8330 is the stronger fit. You are getting 0.5% better PassMark, backed by 4 cores and 4 threads.

Which one is the smarter buy today, not just the cheaper CPU?

Atom x5-Z8330 is still the much better call for a fresh build. Atom x5-Z8330 comes in at an unclear MSRP at unclear MSRP versus $200 MSRP, and it still gives you a 0.2% average FPS lead across 50 shared CPU game tests in our data. Core 2 Duo E8135 only looks stronger on raw value math because it is extremely cheap, but that usually means used-market pricing on an obsolete 2009 platform. Even with 100.0% better value on paper (5.1 vs 0.0 PassMark/$), it really only makes sense as a cheap stopgap or a niche existing-platform option for someone already on P.

Which one is more future-proof for 2026 and beyond?

Atom x5-Z8330 makes more sense long term for 2026 and beyond. You are getting a newer CPU generation (2016 vs 2009) and more multi-core headroom with 4 cores / 4 threads instead of 2/2. That extra compute headroom is more likely to matter as games, background tasks, and creator workloads get heavier.
